Rails + Haml: How to unescape tag parameter?

Question

I'm trying to accomplish the following content in source code:

<div id="box<%=id%>"></div>

Without escaping any signs in Haml.

%div{ :id => "box_<%=id%>" }

produces

<div id='box_&lt;%=id%&gt;'></div>

Right now the only way I can do this with Haml is to use :plain filter and hardcode HTML without using any View Helpers. How can I fix that?

I need this because I'm forced to follow this convention because of third-party syntax convention: JavaScript Micro-Templating

Answer 1

You say you're coding in Haml, but the brackets indicate Erb.

• Step 1. Try normal Ruby interpolation:

  %div{ :id => "box_#{id}" }
  

• Step 2. There is no step 2.
